Houston, Texas

Patent attorneys in Houston

Houston, Texas is home to 1,206 USPTO-registered patent practitioners. Working with a local practitioner can streamline in-person meetings for invention disclosures, signing inventor declarations, and reviewing prior-art search results — but every USPTO practitioner is licensed to practice nationally, so a non-local choice is also valid. Local firms with the most USPTO-registered practitioners include Shell Oil Company, Caspar Heyl, and Sabic.

Common questions

Do patent attorneys in Houston cost more than the national average?

Patent attorney fees vary primarily by experience and complexity of the invention, not by city. A typical provisional patent application in the US runs $1,500 to $5,000; a non-provisional utility filing runs $5,000 to $15,000. Hourly rates in Houston tend to track the broader Texas legal market.

How many USPTO practitioners list a Houston office?

1,206 USPTO-registered patent practitioners list a Houston mailing address on the OEDCI roster. You can sort by firm size and contact each directly using the phone numbers shown.

Can I work with a Houston practitioner remotely?

Yes. All filings happen through USPTO's electronic Patent Center — no in-person presence is required. A Houston-based practitioner is convenient for local inventor signings and in-person meetings but not a requirement for representation.
